This invention relates to'index devices of' the type having' holders orpanels with iii-r ilex material `on bolli sides thereof.

Objectsot' the inventionare to leive an indication upon ee'chcsidc ol"`such holders or panels of thefscope of the index material. on both sidesthereof. to provide animproved torni ot index striplftor tabs. and

iii .Qeiieral to improve idcvicesoij'this rkind to the end 'that indexitems therein may be more readilii found.

For the purpose of'illustratiiier tlie inveii tion one concreteembodiment thereotis the accoiinpaiiyingr drawings, in fvvhichz j l isan elevational view:

` Fig. y2 is an enlarged `detail ot a Fig. l; f f

Fig. 8 is ay'section` on the line 3-3 of Fie. 2 showinfir the panel inplan; and

Fig. 4' is a plan view of an index strip. The embodiment of theinventionshown for the purpose of illustration comprises'a r pluralityo'tindex holders yor panels .Ac arranged detachablv to support indexstrips or cards B upon bothsides thereof. jIn the form shown panels Aare mounted for swingingY movement upon vertical pivots C in frame Dtodisplay7 the k.iederen'iaterial upon the opposite sides thereof. Eachpanel is provdediupon its outer free edge with a suitable tab E. Thistab inavy be of any sultable form or construction.` one torio` 'beineshown rin elevation iii Fie. 2 and iiil section in 3. The tab comorisesastrip of sheet metale fast at one end between the sides a of'one ot thepanels, lthegoiiter end` of metal. strip e heinfr bent iiito .parallelrewill also tell. him iipon which yside of the 95 lation with theremainderot the strip. y*This strip e is preferably7 enclosed orsurrounded by a l,sheath e .of transparentrresilient inateria'l.. suchasa Celluloid. having; ak bent n end e2 enclosiiigthe tree edge oistrip-e and the opposite end e wede'ed between. one of the sides l ofthe panel and the metal. Strip e, whereby the sheath is securelvretained upon the metal strip c. kBetween. sheath e and strip e areinserted index strips F each having index indicia 'thereon such as thenumber otthe panel or each side thereof and an indication ot the scopeor content of the index material not only upon the side upon which thestrip is ap- Y portion 0i one of the holders orfpaiiels shown in" plied`but panel also.

A preferredlorm oi the index strip is.

upon ythe opposite side of the shown in Fir.` whereiiia heavy horizontal1 'i serted in tab directly behind the cellii-. `loid sheatli'e andbetween n `it'and the metal strip e as showny in Fig. 3.

From the above it will beclear that en improved indexv strip has been.provided for li desired the index strips Fi giving aniiidication oneach sidel of a. doubley i faced index panel of the index materialcontent oii both' sides thereof; ment lis particiilarhi useful in lanindex den vice of the 'type such as illustrated shown in Fie. 1, inwhichka pliiralitv of index panels aremonnted for swingingf movement` toopposite sides ktodisplav the index material on the opposite sidesthereof.' In inspertine siieh anindex device aportion of This arrange-rthe panels ywill ordinarilyv be disposed with ftlieir faces toward theuser and ythe other portion kwith their backs towardthe user. Bvproviding such index panels with index strips 'of the tvpe shown theuser `has at kall timee'visible to hiin a complete index of all the.material. iipoii the panels and as soonas yhe determines trom theindication on they several tabs which panel has the item which hedesires to inspect the tab of that'panel panel the item is to be found.since the indicia 4above the horizontal line refers to the items" on theexposed side of the panel and the yindicia below ythe line to thekopposite side of the panel.

While but one embodiment of the invention has been shown it is obvioiisthat many changes and variations mair be made in a daptinu' theinventive idea herein disclosed to vindex s vstems of various kindswithout departing Jfrom the spirit and scope of the invention.

I claim: y

1,111 an index device the combination A with a series of holders havingindex inaeach faceV of said holder.l said indicia indi-V face.
